摘　　要：通过生命周期内对天然气乘用车和汽油乘用车在原材料获取、生产阶段及使用阶段的碳排放对比分析计算,得到天然气车与汽油车在各阶段的碳排放增加或减少变化量,从而确认天然气乘用车碳排放的比较优势。对两款同平台的汽油车和CNG车对比计算分析,CNG车比汽油车在车辆使用阶段的碳排放量有较大幅度的减少,而在原材料获得阶段和整车生产阶段的碳排放量有所增加。生命周期CNG车比汽油车碳排放量减少3655 kgCO_(2)e,单位行驶里程减少碳排放24.37 g CO_(2)e/km,从而达到了对CNG车减少碳排放量进行定量分析。Through the comparative analysis and calculation of the carbon emissions of natural gas passenger cars and gasoline passenger cars in the raw material acquisition, production and use stages in the life cycle, the increase or decrease of carbon emissions of natural gas cars and gasoline cars in each stage is obtained, so as to confirm the comparative advantage of carbon emissions of natural gas passenger cars. Through the comparative calculation and analysis of two gasoline cars and CNG cars on the same platform, it is found that the carbon emissions of CNG cars in the car use stage are significantly reduced compared with gasoline cars, while the carbon emissions in the raw material acquisition stage and the car production stage are increased. In the life cycle, the carbon emission of CNG cars is reduced by 3655 kgCO_(2)e than that of gasoline cars, and the carbon emission per unit driving mileage is reduced by 24.37 gCO_(2)e/km, thus achieving the quantitative analysis of the carbon emission reduction of CNG cars.
